Calling Quentin Tarantino a genius, Jamie told ET, "Every day was just an amazing opportunity to work with people that humble you," adding, "It's a true testament to a community of real actors. I'm the happiest dude in the world."

Leo says of his villainous character, "He's not only a bad guy, he's a horrendously racist, narcissistic, self-indulgent bastard, but he came from the mind of the great Quentin Tarantino, and when you get these opportunities in life, you have to really go for them and not look back." Of Jamie's performance, Leo says, "He's incredibly badass in this film."

In theaters Christmas Day, Tarantino's action-packed follow-up to Inglourious Basterds tracks a former slave-turned-bounty hunter (Foxx) who sets out to rescue his wife (Kerry Washington) from a ruthless plantation owner (DiCaprio) with the help of his mentor, German-born bounty hunter Dr. King Schultz (Christoph Waltz).
